A simple improvisation technique for designing a linear quadratic regulator (LQR) optimal controller for a robotic pan and tilt platform (PTP) with two degrees of freedom (DOF) has been proposed in this paper. Newton-Euler linear model of this robotic system has been stabilized to obtain the desired performance criteria via LQR. The performance of the proposed LQR controller is highlighted through comparisons with the existing proportional derivative (PD) and lead Compensator controllers on account of both steady state and transient response parameters.
This paper proposes a system for automation of appliances which will be operated using sensors and micro controllers. We have used sensor network and one central control section. The network is connected with IR Sensors and relays. Sensors will be in communication with micro controller. Whenever a person enters into a Particular zone, his presence will be detected by IR Sensor and it will send this information to controller. Controller after receiving information from particular sensor, it sends signal to particular relay there then after the appliance will turn on/off due to presence / absence of person. The feasibility of the model is verified in the demo kit.
